TRACK-CLEANING DEVICE Application led Au'rust 19, 1920.

T0 all whom t may concern.'

Be it known that l, SUMNER K. PREsooTT,

a citizen of the United States, and a resident of Seattle, King `County,lVashington, have invented certain new and useful Improvements inTrack-Cleaning Devices, of which the following is a specification.

This invention relates to improvements in track cleaning devices, andmore particularly to devices of that character applicable to the wheelsof cars or carriages such as are used in lumber and saw mills, wherebythe rails on which the wheels travel may be kept clean of saw dust orother debris.

The principal object of the invention resides in the construction of atrack cleaning device in the form of a double ended plow adapted toreceive in operative position the wheel of a car, or carriage, in suchmanner that, during travel of the wheel along a track in oppositedirections, the opposite ends of the plow will clean the track ahead ofthe wheel of all saw dust, dirt or debris which would be detrimental tooperation of the car.

A further object of the invention is to provide a track cleaner of theabove character, wherein removable wearing blocks for the wheel, andothers for the track, are pro vided, and which are mounted in a novelmanner which permits them to be easily removed and replaced when itbecomes necessary. c

In accomplishing these and other objects of the invention, I haveprovided the improved details of construction, the preferred forms ofwhich are illustrated in the accom-` panying drawings, wherein- Figure lis a longitudinal, vertical section of a track cleaning device,constructed according to the present invention, showing in dotted linesthe relation of the carriage or car wheel thereto, when the device is inuse.

Figure 2 is a plan View of the same.

Figure 3 is a front or end view, of the plow in position on a track.

Referring more in detail to the drawings- 1 designates the plow bodycasting which comprises opposite end heads 2 and 3, which are joined inspaced apart relation by means of opposite side or face plates, 4 andThese latter plates extend parallel with each other, longitudinallyr ofthe device and iny spaced apart relation, so that a carriage Serial No.404,678.

wheel may operate between these plates and heads, as is illustrated indotted lines in Figure l.

The end heads are each tapered to a vertical cutting edge 7 along theirforward edges and are provided in their under sides with downwardlyopening pockets 8 for receiving the holding shanks or extensions,`9,

-of plow shoes l0, which are adapted to engage and slide upon a track;these shoes be ing tapered to points at their forward edges tocorrespond to the shape of the plow heads and are` provided withtransverse apertures ll which may he brought into registration withapertures in the body casting to receive locking pins la ywhich willhold .the shoes in place.

Opening inwardly from the inner faces of the end heads are pockets l5wherein wooden blocks 16 are inserted, and which are in position to beengaged by the rim or tread of the wheel whereto the plow is applied;these latter blocks serving to relieve the wheel and casting of wearthat otherwise would occur, and also serve as Scrapers which will removeresinous and other substances picked' up by the portions of the wheel.

The device in use would be applied to a flat treaded wheel of a lumbercarriage, as is illustrated in Figure 1, and would be moved therebyalong the track as ,the car would be operated in opposite directions, insuch Inanner that the plow shoes at its opposite ends would scrape thetrack clean of all dirt or saw dust that might fall on the same.

The wooden blocks would serve as cushioning bumpers, for receiving theimpact of the wheel on the reversal of the car and would prevent wear onthe wheel and casting due to the rolling contact of the wheel with thedevice.

The shoes l0, which would receive considn erable wear, would preferablybe made of hardened metal and would not need to be changed as often asthe wooden blocks, but, such changing would be permitted, when oc casionis necessary, by removing of the pins 14.

`What l claim as new, is:

A track cleaning device comprising a one piece body having plow heads atits opposite ends integral with spaced apart face plates connecting saidheads in such relation so as to receive the lower part of a wheeltherebetween; said heads having inwardly opening the track on which theWheel operates, having mounting Shanks removably inserted in thedownwardly opening pockets.
